SCREW GAP.

Patented July 4, 11922.

Application filed December 13, 1921. Serial No. 521,985. i

To all whom it may concern: 1

Be it known that 1, JOHN M. ABRAnrs, a citizen of the United States, and a resldent of Brooklyn, inthe county of Kings and State of New York, have invented certain new and useful Improvements in Screw Caps, of which the following is a specificatlon.

The invention relatesto caps for containers of various kinds, for example, those used 'in connection with paste tubes; and more particularly to a captive cap, that is to say a cap which may be freely manipulated to open and close the container though held thereto in the opened position in manner such that it cannot become detached from the container or lost and will, therefore, be conveniently accessible if it be desired to again close the container.

The invention has for its object a cap with a non-swiveled connection to the" container and which is composed of a minimum num-' ber of parts, being so constructed as to permit rapid opening and closing of the container; and, furthermore, to provide a cap which is inexpensive in its construction and simple in its operation.

To this end, the invention consists in a rotatable or screw cap member having a nonswiveled' connection with the container, as through a flexible member such as cord or the like, said cap, furthermore, having means thereon for engaging the flexible member to wind same about the cap as the latter is screwed on and rotated for the purpose of closing the mouth of the container.

In the accompanying drawings, which illustrate the invention- Fig. 1 is an elevation of a portion of the container with the improved cap mounted on the neck portion thereof.

Fig. 2 is a vertical section through the container and cap.

Fig. 3 is a plan view. Similar characters of reference deslg- ,nate corresponding parts throughout the several views.

Referring to the drawings, 10 designates a container of suit ble construction and which may be of the pliable type generally known as paste tubes, the same having a neck portion 11 through which the contents are to bedelivered. A cap 12 is designed normally to close this container by fittin over the neck portion 11 thereof, the cap an neck being threaded to admit of screwing the former upon the latter as in rotating same. In order that the cap 12 may not become separated from the neck 11 when the former is removed therefrom to open the container, means are provided tolpermanently attach the cap 12 to the container 10 but in manner so as to admit of the rotation of the cap sufficiently for effecting the opening of the container. To this end, a flexible member, such as a cord 13, is suitably secured at one end to a perforated lug 14 extending from the container 10 and at the other end to a perforated lug 15 extending from the top of the cap 12, the cord being of sufficient length to allow of the cap being unscrewed from the container and not becoming permanently detached therefrom.

In order to dispose of the surplus length of cord so that the cap and cord may present a neat appearance and also not interfere with the operation of opening and closing the container, the cord is most satisfactorily accommodated by being wound about the outer surface of the cap 12, as indicated in Figs. 1 and 2. To insure of such winding of the cord about the surface of the cap, the top of the latter is provided with a plurality of lugs 16 extending outwardly from the circumference of. the cap and which overhang the cylindrical surface of the cap, acting to pick up the cord to cause same to be wound about the said cylindrical surface as the cap is screwed to the neck of the container. In this manner, when the container is not in use, the cord is neatly located about the surface of the cap, as shown. The lugs 16, moreover, are of assistance in unscrewing the cap or returning same to the container, and add but little to the cost thereof, while the use of a cord which forms a nonswiveled connection between the cap and the container entails but a minimum expense for labor and material.

I claim:

1. A container having a threaded neck portion, and a screw cap for detachable engagement with the outer end of the neck, and a flexible member connecting said cap with the container and adapted to be wound about the cap.

2. A container having a threaded neck portion, and a screw cap for detachable engagement with the outer end of the neck, and a flexible member connecting said cap with the container and the said cap having means to engage the flexible member to wind same about the cap.

i).- A; container having a threaded neck portion, and a screw cap for detachable engagement with the outer end of the neck, a cord secured 'to the container and to the top of the cap, said cap having lugs extending outwardly from its upper surface to engage the said cord to wind same about the cap. 4. A container having a threaded neck portion, and a screw cap for detachable engagement with the outer end of the neck,

and having a perforated lug at the top and lugs extending outwardly from the circumference, a perforated lug on the container 15
